Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
CAUTION: The device ports must quiesce before removing the
controller. Failure to allow the ports to quiesce may result in data loss.
Quiescing may take several minutes.
ESD can easily damage a controller. Wear a snug-fitting, grounded ESD
wrist strap.
NOTE: A countdown timer allows a total of two minutes to remove the controller. If
you exceed two minutes, “this controller” will exit FRUTIL and resume operations.
If this happens, return to step 4.
9. Remove the trilink connectors from the “other controller,” but don’t disconnect
the host bus cables (or terminators) from the trilink connectors.
NOTE: One or two trilink connectors with host bus cables (or terminators) may be
attached, depending on the configuration.
10. Disengage both retaining levers, remove the “other controller,” and place this
controller into an antistatic bag or onto a grounded antistatic mat.
Once the controller is removed, FRUTIL displays the following:
Restarting all device ports. Please wait...
Device Port 1 restarted.
Device Port 2 restarted.
Device Port 3 restarted.
Device Port 4 restarted.
Device Port 5 restarted.
Device Port 6 restarted.

11. Enter N(o) if you don’t have a replacement controller; FRUTIL will exit.
Disconnect the PC or terminal from the controller’s maintenance port.
Enter Y(es) if you have a replacement controller and want to install it now.
FRUTIL displays the following:
Insert the slot A [
or B
